1. A photoelectric structure for surface mounting on a circuit board having a plurality of insertion holes, comprising:

  • a photoelectric element comprising a disk body and a chip affixed on said disc body;

    means for surface mounting said photoelectric element on said circuit board, comprising;

    a pair of upright fixation pins parallelly extended from a periphery of said disc body downwardly for directly inserting into two of said insertion holes or said circuit board so as to support said disc body and securely mount said photoelectric element on said circuit board, thereby an area for mounting said chip of said disc body is enlarged by having said two fixation pins supporting said disc body securely, and a pair of bended rigid connection wires, having a width larger than said fixation pins, each of which is positioned between said pair of fixation pins and integrally bent in L-shaped to define a vertical upper portion and a horizontal lower portion, wherein a top end of said upper portion of one of said connection wires is positioned adjacent to said periphery of said disc body for functioning as an electrode of said photoelectric element while a top end of said upper portion of said another connection wire is integrally extended from said periphery of said disc body, wherein said two lower portions are perpendicularly extended from said upper portions respectively for resting and fastening on said circuit board by welding so as to electrically connect said photoelectric element with said circuit board, thereby a constant height of said chip and said disc body being positioned above said circuit board is ensured by said upper portions of said connection wires; and

    a sheath, made of an epoxy resin material, shielding said photoelectric element, said upper portions of said pair of connections, and upper portions of said pair of fixation pins by injection molding.
